Toschi Castelli
It's an "Ordinanza Italiana 1889 Mod. A" (Italian Ordnance 1889 Model A) caliber "10,4mm Ordinanza Italiana", produced in 1916 by "Toschi Castelli - Brescia", one of the many private factory that worked for the Italian Army.
It was an important factory, and your gun is a good gun in nice conditions.
The crowned RE is the mark of "Regio Esercito" (Royal Army). The mark in image is the proofmark of the Bench of Ulm: the revolver was in Germany during its life (probably in 1969), this isn't an italian mark.
"14" and other two-digit numbers are assembly numbers. L8055 is serial number. RP in the oval is Inspector's mark. HEGE is a German importer/seller.
Hoping to be useful to you
Best regards
